What I claim is:

l. A Window ventilator comprised of a main body portion of sheet metalhaving integral ears at the ends, air admission perforations and airdelectors, and extensions in connection With the ears at the ends; thesaid main body portion and ears being formed of a single sheet of metalhaving parallel lines of perforations and the projecting ears, the metalbeing bent lengthwise on lines each side of the lines of perforations toform alternate longitudinaly air delecting and air admission partsangularly disposed to one another, the integral ears bent at rightanglesy to the said longitudinal parts,y and the extensions secured tothe ears at oppositeends of the body portion.

2. A Window ventilator comprised of a main body portion of sheet metalhaving integral ears at theiends, air admission perforations and airdelectors; metallic end pieces; and extensions in connection With themetallic end pieces; thesaid `main body portion and ears being formed ofa single sheet of metal having parallel lines of perforations and theprojecting ears, they metal being bent lengthwise on lines each side ofthe lines of perforations to form alternate longitudinal air deectingand air admission parts angularly disposed to one another, the integralears being at right angles -dinally disposed relative to one another,

ears at the ends of the said body portion, and extensions in connectionWith the ears.-

4. A Window ventilator comprised of a main body portion of sheet metalhaving a plurality of air deflecting and perforated air admission partsangularly and longitudinally disposed relative to one another,

ears at the ends of the body portion, metalf lic end pieces secured tothe ears, and addiltional pieces in connection With the end pieces. l o

5. A Window ventilator comprised of a main body portion of sheet metalhaving a plurality of air deiiecting and perforated air admission partsangularly and longitudinally disposed relative to rone another, integralears at the ends of the body portion, end pieces secured to the ears,and Wooden pieces in connection With the end pieces.

In testimony whereof I aix my signature, in presence of tvv@ Witnesses.
